The B-24J was very similar to the B-24H. Because of shortages of Emerson nose turrets, Consolidated re-engineered the basic Liberator design to accept a modified version of the A-6 tail turret in the nose. Consolidated which became Consolidated-Vultee in March 1943--used the basic (late model) B-24D design as a starting point for the -J model. Improvements in the Ford-built -H model were not incorporated into the initial -Js. For example, the defensive improvements gained by the staggered waist gunner position and the 'High-Hat' top turret did not appear in early Consolidated B-24Js.

Late model B-24Js were similar, but slight variations between assembly plants required repair facilities to carry up to 5 different sets of parts. The B-24J was built by Consolidated at their San Diego and Fort Worth plants, by Ford at Willow Run, Douglas at Tulsa and North American at Dallas. The B-24G, -H and -J models were all very similar and difficult to distinguish in some cases. Without a visible serial number, identification is almost impossible for certain subtypes. For example, Ford supplied B-24H subassemblies to Consolidated to build at their Fort Worth plant, but these aircraft were given B-24J serial numbers.

The B-24J had an improved auto pilot (type C-1) and bomb site (M-1 series). When B-24H and B-24G-1 aircraft were retrofitted with these improvements, they were redesignated as -J models which also makes absolute identification difficult.
